Executive SummaryThere is a critical need for lossless data compression in enterprise storage and applications such as Databases, which process huge amounts of data. DEFLATE is a widely used standard to perform lossless compression, and forms the basis of utilities such as gzip and libraries such as Zlib. In these applications, decompression imposes a large computational burden on the servers, and they could benefit from a highly optimized implementation.This paper describes the performance characteristics of an optimized implementation of DEFLATE decompression, on Intel® processors based on the 32nm microarchitecture. As the performance of decompression is data dependent, we report the performance on various industry standard corpora data sets.
